You are an entrepreneur who is deciding the operational plan for your business.
While deciding the technology to be used, you come across three alternatives:
a) Use a cheaper technology which lets you dispose of the waste water and lets
you fix the price of your product low.
b) Use a technology that is a little expensive as it lets you recycle that waste water
into water fit for drinking. In this case, you will have to fix the price a little
higher in order to earn profits.
c) Use the technology that recycles the waste, do not change the price. And go
about cost cutting though efficient utilization of resources.
